greylisting?

[Damian Mendoza]

It's the only way that I'm able to stop the 5% of spam that keeps
getting past RBLs, SURBLS, SpamAssassin, Stearns blacklist,
rules_du_jour, etc.

It will reduce the load on your server as I don't have to process a
message for Spam since greylisting runs at the sendmail level. I can
support 120,000 plus messages per day with a single P-4 processor and
1GB memory


Regards,

Damian

Subject: greylisting?

Hi Everyone,

We're catching loads of spam, but would like to take it to the next 
level. From a bit of reading I'm doing, this may be some implementation 
of greylisting. That said, I'm new to the concept of greylisting but it 
seems to make some sense. We're using Sendmail on our server; how easy 
and effective is greylisting? Does it add extra load to the server or 
anything?

Thanks,
Chris
